Broadband Acoustic Sensing with Optical Nanofiber Couplers Working at the Dispersion Turning Point
Herein, a broadband ultrasensitive acoustic sensor based on an optical nanofiber coupler (ONC) attached to a diaphragm is designed and experimentally demonstrated. The ONC is sensitive to axial strain and works as the core transducing element to monitor the deformation of the diaphragm driven by aco...
